IMPROVEMENT IN COACH-PAD TREES.

Specification forming part of Letters Patent No. 177,081, dated May 9, 1876 application filed September 9, 1874.

cast in one piece, may the more readily, if desired, be made in great numbers,'of uniform size and shape.

Heretofore harness-pads have been made with their plates in separate pieces, the bottom piece being struck up and fitted to the top piece, and the two united together mainly by the leather coverin Such harness-pads are more complicated in structure, more diffivcult to cover and finish, and are more likely to get out of repair than a harness-pad built upon the'plate or tree hereinafter described.

This invention, therefore, consists in a pad plate or tree cast substantially in the form illustrated in the drawing, and having but one piece or web to form both'its top and bottom, which web is'provided with suitable flanges.

In the drawing, A is the main body or web of the plate or tree. a is a perforated flapge, to which the leather covering may be secured. b is a hole in the main body or web A, through which either a check-hook or a terret may be inserted, and secured by means. of a nut in therecess c. d is a perforated web cast over a recess in the main web A, which recess is open at one end, and partially closed on top by the perforated web d. Into this recess is passed an ordinary burr or terret-nut, having its shoulder projecting up through the hole d in the web d, and secured in place by a thin strip of metal, 0. v

This strip may be riveted at either end to the web A, if desired. The burr can thus be removed, when repairing the pad, by either sliding orspringing down the strip 0 Withoutcutting off any rivets.

' Burrs, as ordinarily secured, are riveted through their flanges to the tree or plate, which rivets must be cut, in order to remove said burrs.

Between the ribs 9 9, cast upon the top of the main web A, are placed'ordinary burrs or nuts, for receiving necessary screws, terrets, or hooks. These burrs or nuts so held likewise require no rivets to secure them in place.

It is evident, however, that the necessary burrs or nuts may be secured to the web A in any manner desired Without departing from the principle of my invention of casting a pad saddle I mean the article known by such name to harness-makers,which is used only for single harness. Byia coach-pad or harness-pad 1 mean the article known by such name to harness-makers, and which is used only for double harness.

Having thus fully described vthis harnesspad plate as of my invention, I claim- As an article of manufacture, a harness-pad plate or tree cast in one piece, in the ."shape substantially as described, consisting of a main body-or web, A, provided withperforated flanges a, recessed web 0?, and ribs 9 g,-

in the manner substantially as described, for the purposes set forth I In testimony that I claim the foregoing as my own invention I affix hereto my signature in presence of two witnesses.
